In 1262 Walter acquired lucrative sinecures such as the new prebendary of Exeter, and became a canon of Wells Cathedral. The following year, when de Montfort was at the height of his powers, Walter was urged by the bishop of Worcester to accept a form of peace satis competens et honesta.[3] It is possible that Walter was a member of Richard of Cornwall's deputation sent from Windsor to greet Montfort's army coming east from London and Kent. But on 16 July, when the King surrendered peace terms, and three days later de Montfort assumed power, Walter also left office.[4]
